Granted this doesn't take into account the marketing budget or the theater/distributor cuts of the box office.

What's the deal with theater/distributor cuts? I heard they don't get much, and rely on snack sales, but you'd think it's still a significant cost. While supposedly the marketing budgets can be close to the size of production budgets. Yet doubling the production budget is considered a financial success? Sounds like in a way blockbusters are made for dvd lol.

Of course some get closer to tripling the production budget (I thought the new Treks did this), or more.
